Thanks for posting all these "rejected" designs! Some I find quite attractive, others ... With regard to the EU Enlargement coin, the minted design (Mieras) has a good reverse, but I am not fond of the Queen's portrait.

The country codes used by Fortuyn would have been fine, I think. (After all, the minted €10 coin used the very same approach, except that Nederland is spelled out, and the others are 1 to 3 character codes ... from car license plates, I suppose.) Not sure why Fortuyn would use the ISO codes two times though. And the flower may indeed have been difficult to understand.

Kaper's handjeklap I do not like. Whose hands would that be? The European Union reaching out to the one hand of the ten new member states? And the text "Europese Unie" does not make it much better ...
